When the force is applied, if the tool is not rigid enough, the tool body will deform, and a deviation will be produced in the direction of the force, and there will be a displacement. The tool has a displacement, so the depth of the knife will be smaller, the force will be smaller, and the displacement will be smaller. The generated displacement becomes smaller, and the tool moves in the opposite direction of the force, so that the cutting depth becomes larger, and the cutting becomes larger at the same time.

This is like comparing a tool to a long and thin wooden stick. One end is fixed and the other end is stressed, so the end away from the unfixed end will be deflected and rebound.

In this way, during the machining process, constantly changing cutting forces act on the tool and the workpiece, resulting in vibrations.

Chip formation and chip evacuation are key issues in drilling and depend on workpiece material, choice of drill/insert geometry, coolant pressure/volume, cutting parameters.

Drilling processing, there are three basic conditions for selecting a drill bit: material, coating and geometric characteristics.

In factory communication, many people are accustomed to using the term "surface finish". However, "surface finish" is proposed from the perspective of human vision. In order to conform to the international standard (ISO), the national standard no longer uses the term "surface finish". Therefore, in formal and rigorous expressions, the word "surface roughness" should be used.

Surface roughness refers to the small spacing and the unevenness of small peaks and valleys on the machined surface. The distance (wave distance) between the two peaks or two troughs is very small (below 1mm), which belongs to the microscopic geometric shape error. The smaller the surface roughness, the smoother the surface.

Tool with two insets are used to cut quadrilaterals, and with three insets are used to cut hexagons, etc. If a different gear ratio is used or if the number of cutting edges of the tool is changed, large depressions or prominent deflection arcs may appear on the workpiece surface.

In the process of NC programming, in order to make the programming work more convenient, the tip of the NC tool is usually imagined as a point, which is called the tool point or tool tip point.

According to the actual size of the tool, the CNC machine tool automatically changes the coordinate axis of the machine tool or the position of the tool tool point, so that the actual machining contour and the programmed trajectory are completely consistent, which is called tool compensation ("tool compensation" on the system screen) function.

The chuck soft jaw of CNC lathe is a device for clamping the workpiece. It is a relatively soft jaw that has not been heat-treated, and can be processed according to the shape of the workpiece to improve positioning accuracy²³. Soft claws have different specifications and shapes, such as 6" soft claws, 8" soft claws, 10" soft claws, thickened, widened, square, pointed soft claws, etc.

Drilling, while deceptively simple, is actually a complex process in which a drill bit malfunctioning or exceeding its capabilities can have serious consequences. Drilling non-planar workpieces may subject the cutting edge of the drill bit to excessive and uneven forces, resulting in premature wear, be sure to pay attention to the points mentioned below.

Tool setting of CNC lathe is an important skill in processing. The accuracy of tool setting determines the machining accuracy of parts. The efficiency of tool setting directly affects the processing efficiency of parts. Tool setting is very important to the machining operation of machine tools.

In metal cutting, some chips are rolled into coils and break off when they reach a certain length; some chips are broken into C-shaped and 6-shaped; splashing around, affecting safety; some strip-shaped chips are wrapped around the tool and workpiece, which is easy to cause accidents. Poor chip removal status will affect the normal production. The use of chuck soft jaw.

CNC lathe is a kind of mechatronics equipment with high comprehensive performance. For CNC lathe, it has some advantages. Its processing precision is very high, which can improve production efficiency, reduce labor intensity of workers, and promote the comprehensive processing of processing enterprises. It is precisely because of these advantages that it has been widely used in many manufacturing fields. Whether the choice of CNC machine tools is reasonable is closely related to the processing quality and production efficiency. Undesirable effects due to normal processing.

The optional auxiliary for a CNC lathe can vary depending on the specific machine and its configuration. However, some common optional auxiliaries that can be added to a CNC lathe for enhanced functionality and capabilities.

Obviously, CNC lathe is the most popular Lathes on the market, and let’ study more about it. CNC means Computerized numerically controlled, which is widely used as a lathe in modern society because of its fast and accurate working.

The machine tool is controlled by computer programs. Once the program is loaded into the computer, it begins to operate at a high rate and with great accuracy. Even a preplanned programmed machine exists, in which once the code for the various tasks is set, the machine may begin operating without having to change the code again. After the initial setup, a semi-skilled worker may readily run it. These sorts of lathes, like capstan and turret, are also utilized for mass manufacturing, but there is no programmed feeding system. These lathes produce components with extremely tight dimensional tolerances.

CNC lathe is a computer-numeric controlled machine tool specialized in CNC turning machining, including taper turning, hard turning, spherical generation, facing, cutting off, knurling, drilling, grooving, etc. Compared to a conventional lathe, CNC lathes are operated with precise design instructions and programs to improve the productivity and precision of CNC machining demands.
